Claims.

This invention relates to rear compartment locks for automobile bodies.

Rear compartment locks ordinarily are designed to have a locking arrangement in which the handle is connected with one or more sliding bolts or one or more clamps. The-connection between these bolts or clamps and the handle is a positive one. The device for preventing the turning of the handle is usually some form of small sliding bolt. Hence, it is possible toput a tool; such as a-pipe, over the handle and force the look by means of breaking the'small bolt that prevents the turning of the handle spindle. Y

It is the object of the present invention to provide a free-wheeling handle so that when the compartment is locked with a key the handle is disconnected from the locking parts so these-can- I not be forced and broken. This is. an oldide'a in connection with the side door locks of automobiles, but so far as I know it has not been used with rear compartment locks. Most of these side door locks in which this principle is worked out employ a pin tumbler form of lock which is embodied in the end of the handle spindle and it is relatively an easy matter to provide some form of clutch operated by the key barrel and lying between the handle and the handle spindle.

In the present invention the key barrelis not located at the end of the handle spindle and a problem is presented of providing a suitably operatedkey or clutch device between the handle spindle and one of the operating parts of the look. I believe that I have solved the problem by providing a very efficacious disconnectable drive between the spindle and the lock part; at the same time one that involves a very simple arrangement of parts.

Referring to the drawing:

Fig. 1 is a vertical section through the lower part of the rear compartment lid and an adjoining part of the body showing the lock in section.

Fig. 2 is a section on the line 22 of Fig. 1.

l designates the automobile body just below the rear compartment opening. 2 is the rear compartment lid which has an overlap flange 3 which closes against the rubber Weatherstrip 4. 5 is the rear compartment lid inner panel and secured to this by welding'or otherwise is a lock plate 6. The lock involved here is the pull hook type, such as shown and described and claimed in the Wise application, Serial No. 366,365 filed November 20, 1940.

This hook type of lock has a slide 1 which is guided vertically by the turned-over lugs 3 slide 1 is caused to move downwardly in the housing 9, pin 10 pushes the hasp with its hook I6 first downwardly to free the same from the keeper H, as shown in the dotted lines of Fig, 1. In pushing the hasp down, the pin I 4 slides in the vertical portion of the slot l5 to permit the downward movement of the hook l6. Thereafter, the pin ii], in pushing on the end of the hasp, causes the hasp to pivot on the pin l4 and swing up through the are shown by the arrows in Fig. 1. These arrows represent the path of travel of the lip [8 of the hasp. However, this is more fully described and shown in the aforesaid Wise application serial No. 366,365. The details are not further shown nor described for the exact form of the clamp or the locking mechanism is immaterial so far as the invention to be here inafter claimed is concerned as this involves a special disconnectable key between the operating member of the lock and the shaft regardless of whether the lock mechanism is a swinging hasp type of lock to clamp the lid securely in place or is some other form of lock.

The slide 1 is operated by a link l9 which is connected with a crank arm 20 which has a hub 2i which is rotatable upon lock spindle 22. The lock spindle is provided with a recess 23 in which may slide the key pin 24. Ordinarily this pin 24 is out of the recess as is shown in Fig- 2. The pin is guided in a hole 25 in the sleeve 26 which is an integral part of the hub 2| of the crank. The coil spring 2'! engages against the end of the sleeve and bears against the head 28 of the sliding pin and ordinarily, when the lid is closed and the key turned to locked position, keeps the pin disengaged from the recess in the spindle, as shown in Fig. 2. Hence, the handle is disconnected from the crank 20 and if the handle is now turned, the handle revolves freely Without operating the lock or clamp.

In order to release the clamp and swing it upwardly, a key 29 is placed in the cylinder lock 30. The key turns the barrel 3| which has a square opening engaging over the squared end 32 of the shaft 33. Passing through a slot 34 in this shaft is the end of a scroll type of cam 35. When the key barrel is turned this causes the shaft 33 and the scroll cam to turn from the full-line of the housing 9. The lower end of this slide position shown in Fig. 2 to the dotted line or high position shown in Fig. 2, raising the pin to the dotted-line position shown in Fig. 2. The handle 36 may now be turned and the pin 24 fastens the crank hub 2| to the handle spindle 22. This causes the crank 20 to pull down on the link I9 as shown in the dotted lines of Fig. 2, pulling the slide downwardly, as shown in Fig. 2, and causing the hasp to first drop to the dotted-line position, shown' in'Figfil; and continued rotation of the handle causes thehasp to swing'np'thrdugh the are described by the arrows in Fig. 1 to a position substantially parallel with the compart- ,ment lid 50 as to be out of the way and-not-project any substantial distance to afford anobstruction on which ones head may b bumpedg as' fully explained in the Wise applicationfflelial No.

After the scroll cam has xbeen turned -hy the key to the lift the pin, it is necessary to keep the parts in that position while the handle'and'the aspindle are turned 'th-rough substantially -a iquarterrof a turn, To so retain the pin the'guide flange-31 is struck out of the housing-plated. s'llhis has the form of ten arcuateitrack which :cetains the pin,-as shown'in the-dotted-line position A, Fig.-2. By swinging the rear-deckdid handlewlli through aquarter ofa turn,- slide-1 is given "enough movement to swing the hasp through substantially 180". p when the "lid 1 is closedand the handle turned back to the vertical r position shown inFigs 1, the pin dropsofl the candiofthe track S'IVand-a spring 21 returns it to its :disoonnectedi position after the key 29 has been "turned to' removethekey which turns thescroll 35 to its lowermostposition.
